I fell in love with paper lanterns last year when i decided i wanted them for my reception tent decor. Paper lanterns are a fun way to add color and beauty to your wedding decor.  In febuary i started researching on how to light my lanterns and the tent. I came across  Mrs Tiramisu post on weddingbee.com.

Using this as my inspiration and guide, i did a mock up of my DIY lights and tested it on a 12 inch lantern.  Here is what I used:

1) Tape

LED lights 100 pieces of  10mm 25000mcd LED Lamp -Ultra Bright White  purchased for ebay user (led-hk) for $13.99 

Fishing line

Batteries 100 Lithium CR2032 CR 2032 3V Cell Button Coin Battery purchased of ebay for $17.00

1) I taped the legs of the LED light to the battery (+ve to Negative & vice versa) to get it to work.

 I also taped the fishing line to the light so the battery so i could suspend and hang it within the paper lantern.  I left the lantern on for 4 days and it was still going strong after that. For the 12 lantern, using 2 per lantern gives it maximum light.

*** Total cost:   ~ $36.00** for 100 pieces of LED lights for paper lanterns

How cool is that!

I'm doing six LED lights each for fifty of my paper lanterns.  I'm using Westinghouse stick-up light bulbs for 27 (larger) paper lanterns.  And I've got 50 small paper lanterns that are battery operated.  Details are here.  I'm really excited about this--I figure having so many lanterns in different sizes and colors will provide a lot of visual interest at an evening reception.

how cool, I didn't know it could be that easy...thanx for posting
